I have not tried it, but is it possible to set a pipeline parameter to zero and then using a mapper to increment the value?
Pipeline parameters are discussed here: https://docs-snaplogic.atlassian.net/wiki/spaces/SD/pages/1438254/Pipeline+Properties
Not sure if there is a Snap that does this type of thing directly, you might need to use the Script snap.
Alternatively, you can use the GroupByN snap to collect all of the documents into a single big document, use the expression language to operate on that, and then split the docs out again.
Pipeline parameters cannot be changed during the execution of a pipeline.
